The present invention provides a window structure which is easily constructed and less expensive to produce than prior art window structures. The window structure includes a metallic sash having an L-shaped cross section which retains an insulated window lite containing a plurality of panes of glass. Glazing tape is placed on the portions of the L-shaped sash which are in plane with the panes of glass and the window lite is seated on one or more setting blocks located on the weight bearing structure of the sash. The window lite is securely mounted to the sash with a silicone adhesive which bonds the edges of the panes of glass to the sash. The silicone adhesive also acts as a thermal break to reduce heat transfer between exterior and interior sides of the window structure. The window structure of the present invention is elegantly simple in comparison to prior art structures since it takes advantage of the inherent rigidity of insulating window lite structures. In addition, the window structure of the present invention accommodates thicker window lite structures which increases the thermal efficiency of the window structure.
